I have not tried freezing this, but I made 1/2 recipe, which seems to be pretty accurately equevalent of 1 box of cake mix. It worked wonders for me and will be happy using it in recipes in future, too.
I'm so sorry, but this just did not work out for me. I froze it for 4 days, then scooped it into a small springform pan. It didn't rise well. I checked my baking powder, and it is still quite active, so I'm not sure what went wrong. I will keep trying until I get it just right. Made and reviewed for Bevy Tag - Thanks :)
